Refrigeration unit temperature alarm using thermal properties of food to eliminate false alarms

A method for sensing the temperature of a refrigeration unit, comprising:

• providing said refrigeration unit having an initial inside temperature below a threshold value;
• providing one or more food products into said refrigeration unit;
• providing into said refrigeration unit a temperature sensing unit, wherein said temperature sensing unit measures inside air temperature of said refrigeration unit;
• establishing a communications link between said temperature sensing unit and a remote computing device, wherein said computing device is configured to determine thermal properties of said one or more food products;
• transmitting from said temperature sensing unit to said remote computing device, temperature data corresponding to said inside air temperature of said refrigeration unit;
• upon detection by said temperature sensing unit of a temperature above said threshold value, determining on said computing device based on said thermal properties, time needed for said one or more food products to spoil;
• determining on said computing device based on said thermal properties, time needed for said one or more food products to return to said threshold value;
• and
• providing an alarm signal if said computing device determines that said time needed for said one or more food products to spoil is less than time needed for said one or more food products to return to said threshold value.
